8. Reference CircuitThis chapter shows a different combination of reference circuits. Before getting started,

please read below notes carefully because it is applied to all the reference circuits.

⚫ 32MHz crystal and RF (VDD) DC/DC inductor (Reg1) are already inside the module.

⚫ Module is pre-programmed with Raytac testing code. Default is using LDO mode

and need to add external 32.768khz to work.

You can use DC-DC mode without adding external 32.768khz, they are NOT related

events.

⚫ When using internal 32.768khz RC oscillator, please remove X2 / C12 / C13.

⚫ When NOT using NFC, please remove NFC1 / C19 / C21.

10. Notes and CautionsModule is not designed to last for a lifetime. Like general products, it is expected to be worn

out after continuous usage through the years. To assure that product will perform better and

last longer, please make sure you:

⚫ Follow the guidelines of this document while designing circuit/end-product. Any

discrepancy of core Bluetooth technology and technical specification of IC should refer to

definition of Bluetooth Organization and Nordic Semiconductor as final reference.

⚫ Do not supply voltage that is not within range of specification.

⚫ Eliminate static electricity at any cost when working with the module as it may cause

damage. It is highly recommended adding anti-ESD components to circuit design to

prevent damage from real-life ESD events. Anti-ESD methods can be also applied in

mechanical design.

⚫ Do not expose modules under direct sunlight for long duration. Modules should be kept

away from humid and salty air conditions, and any corrosive gasses or substances. Store

it within -40℃ to +125℃ before and after installation.

⚫ Avoid any physical shock, intense stress to the module or its surface.

⚫ Do not wash the module. No-Clean Paste is used in production. Washing it will oxidize

the metal shield and have chemistry reaction with No-Clean Paste. Functions of the

module are not guaranteed if it has been washed.

The module is not suitable for life support device or system and not allowed to be used in

destructive device or systems in any direct or indirect ways. The customer agrees to

indemnify Raytac for any losses when applying modules in applications such as the ones

described above.
